Project description
Development Tests
STRENGTH TESTS
Strength tests are performed to obtain data on the state of a test article when exposed to external and internal loads. Strength test articles include aerospace equipment, engineering products, power industry equipment, building structures, models, fragments of products, etc.
The test articles can be subjected to static and dynamic loading, with test parameters recorded and subsequently processed. Models of loading equivalent to actual operational loading are built, data are collected, recorded, and processed, and the tests are controlled from information-computer systems.

External load tests
A wide range of static strength and stability tests is run under concentrated and distributed loads, reproducing any combination of forces required.
The tests by a combination of loads are performed in manual and automated modes.
| Loading, tf | від 2 до 300 |
| Test article size, m | 30х10х18 |
| Deformation measurement range, % | 0,3…2 |
| Displacement measurement range, mm | 0…1500 |
| Measurement channels | 96 |
Mechanical characteristics of materials are measured under load of up to 200 tf.
The test articles are subjected to external pressure of up to 10 kgf/cm2 by vacuum degassing in dedicated degassing chambers.
